Hello & welcome
OK the only differences are, suspension is stiffer at the rear to accommodate the extra weight over the impreza and the exhaust is slightly longer.
Being jdm the ratios in the box and diffs are different but if you had to the entire lot can be swapped for uk running gear,
You've already got bigger wheels so 4 pots and 294mm discs will bolt straight up.
The rear arb is pathetic so I'd change it out for something thicker from an impreza.
Wind deflectors are like rocking horse !Removed! you may have to get a pair shipped from Japan, unless you can find a breakers here that may have one,
If your wanting to map it you'll need a standalone apexi ecu or esl board grafting onto your existing ecu
